CREAM AERATOR.

. Application filed June 9,

This invention relates to a cream aerator and more particularly to a device of this character which may be produced in the form of an attachment for cream separators.

An important object of the invention is to provide a device of this character which may be readily attached to existing cream separators without altering the present construction thereof and which will cool the cream as it is delivered from the cream spout. I

A further and more specific object of the invention is to provide means for mixing a blast of air with the cream as delivered from the spout of a cream separator.

A still further object of the invention is the pro-vision of a device of this character of such construction that the means for pro ducing the blast of air may be operated from the driving mechanism of the separator.

'lhese and other objects 1 attain by the construction shown in the accompanying drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein Figure 1 is a side elevation partially in section embodying a cooling attachment constructed in accordance with my invention;

Figure 2 is a view similar to that shown in Figure 1 but at right angles thereto;

Figure 3 is a detail sectional view through the fitting connecting with the cream spout;

Figure 4 is a section on the line 4-4 of Figure 1;

Figure 5 is a plan view of the agitating propeller.

Referring now more particularly to the drawings, wherein for the purpose of illustration I have shown portions of a well known type of cream separator, the numeral indicates a drive gear of the separator and 11 the cream outlet spout thereof. In accordance with my invention, 1 provide a. shaft 12,

the pinion 13 meshing with the drive gear 10 and likewise secure to this shaft the impeller 14 of a centrifugal fan, the casing of which is designated at 15 and the outlet at 16.

I further provide a Y-fitting 17, one arm 18 of which is adapted for engagement with the outlet end of the cream outlet spout 11 and the other arm 19 of which is connected by a flexible conduit 20 with the outlet .16 of the impeller casing 15. The stem 20 of the Y-fitting is reduced below the point of connection of the arms 18 and 19 to form a seat 192?. Serial No. 19

the central portion of which g 23 for a shaft 24 mounting It will be obvious that in the operation of the cream separator, a blast of air will be directed through the conduit 20 and arm 19 against the propeller 25, causing the same to rotate and the through the arm reby agitate cream entering 18 from the spout 1.1. This agitation will cause the air and cream to properly m termmgle, so that-a maxnnun'i cooling action of the cream can be obtained from the blast.
